Description

Technical Field

[0001] This utility model relates to the field of heat sink technology, specifically an easy-to-disassemble heat sink. Background Technology

[0002] A heat sink is a device used to dissipate heat from electronic components in electrical appliances that are prone to overheating. They are mostly made of aluminum alloy, brass, or bronze and can be in the form of plates, sheets, or multiple sheets. For example, the CPU in a computer requires a fairly large heat sink, and the power transistors, horizontal output transistors, and power amplifier transistors in a television all require heat sinks.

[0003] As integrated circuits develop towards high-density integration, they generate more and more heat, and their temperatures also rise accordingly. In order to ensure the stable operation of integrated circuits, heat sinks are often used to dissipate heat. However, existing heat sinks are mostly monolithic structures, which makes assembly or disassembly extremely inconvenient, lacks versatility, and is not convenient for people to use. Therefore, those skilled in the art have provided an easy-to-assemble and disassemble heat sink to solve the problems mentioned in the background art. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4In this embodiment of the utility model, an easily detachable heat sink includes a first fixing plate 1 and a second fixing plate 2. A first convex block 3 and a first concave block 4 are fixedly connected to the front and back of the first fixing plate 1, respectively. A second convex block 5 and a second concave block 6 are fixedly connected to the front and back of the second fixing plate 2, respectively. The second convex block 5 is engaged with the first concave block 4. A heat sink body 7 is provided on the top of both the first fixing plate 1 and the second fixing plate 2. A positioning block 8 is fixedly connected to the right side of the first fixing plate 1 and the second fixing plate 2, located at the front and rear ends of the heat sink body 7. A connecting plate 9 is fixedly connected to the right side of the heat sink body 7. The right side of the positioning block 8 extends into the interior of the connecting plate 9. A disassembly mechanism 10 is provided at the front and rear ends of the right side of the connecting plate 9.

[0024] The disassembly mechanism 10 includes a locking block 101, a fixing block 102, a spring 103, and a push rod 104. One side of the locking block 101 passes through the locking block 101 and extends into the interior of the connecting plate 9. One side of the fixing block 102 is fixedly connected to the other side of the locking block 101. One side of the spring 103 is fixedly connected to the other side of the fixing block 102. The other side of the spring 103 is fixedly connected to the inner wall of the connecting plate 9. The left side of the push rod 104 passes through the connecting plate 9 and is fixedly connected to the fixing block 102.

[0025] By setting up a locking block 101, a fixing block 102, a spring 103, and a push rod 104, the heat sink body 7 can be assembled or disassembled under the action of the locking block 101, the fixing block 102, the spring 103, and the push rod 104, thereby facilitating the user to adjust the number of heat sink bodies 7 according to actual usage needs and improving the versatility of the heat sink body 7.

[0026] In this embodiment, a placement slot 11 is provided on the right side of both the first fixing plate 1 and the second fixing plate 2. There are several placement slots 11, which are equidistantly distributed. The bottom of the heat sink body 7 passes through the placement slot 11 and extends to the bottom of the first fixing plate 1 and the second fixing plate 2 respectively. By setting the placement slot 11, the heat sink body 7 can be placed under the action of the placement slot 11, thereby facilitating the movement of the heat sink body 7.

[0027] In this embodiment, the surfaces of the first fixing plate 1 and the second fixing plate 2 are provided with sliding grooves 12 at the front and rear ends of the placement groove 11. A slider 13 is slidably connected inside the sliding groove 12. One side of the slider 13 is fixedly connected to the heat sink body 7. By setting the sliding groove 12 and the slider 13, the heat sink body 7 can be moved under the action of the sliding groove 12 and the slider 13, thereby achieving the purpose of restricting the position of the heat sink body 7.

[0028] In this embodiment, a disc 14 is fixedly connected to the right side of the push rod 104. The right side of the disc 14 is provided with anti-slip texture. By providing the disc 14, the user can easily move the push rod 104 under the action of the disc 14, thereby achieving the purpose of making it convenient for the user to push the push rod 104 to move.

[0029] In this embodiment, through holes 15 are provided at both the front and rear ends of the right side of the connecting plate 9. The push rod 104 is located inside the through hole 15. By providing the through hole 15, the push rod 104 can be placed under the action of the through hole 15, thereby facilitating the movement of the push rod 104.

[0030] In this embodiment, positioning grooves 16 are provided at both the front and rear ends of the left side of the connecting plate 9. The right side of the positioning block 8 is located inside the positioning groove 16. By setting the positioning groove 16, the positioning block 8 can be placed under the action of the positioning groove 16, thereby facilitating the user to position the connecting plate 9.

[0031] In this embodiment, grooves 17 are provided at both the front and rear ends of the connecting plate 9. The locking block 101, the fixing block 102, and the spring 103 are all located inside the grooves 17. The right side of the grooves 17 is connected to the through hole 15. By setting the grooves 17, the locking block 101, the fixing block 102, and the spring 103 can be placed under the action of the grooves 17, thereby facilitating the movement of the locking block 101 and the fixing block 102 and the extension and retraction of the spring 103.

[0032] The working principle of this utility model is as follows: When the user needs to adjust the number of heat sink bodies 7 according to actual usage, the second convex block 5 can be pressed into the interior of the first concave block 4, so that the first fixing plate 1 and the second fixing plate 2 are engaged. By repeating the above operation, multiple first fixing plates 1 or second fixing plates 2 can be engaged, thereby increasing the number of heat sink bodies 7, which facilitates heat dissipation for integrated circuits of different sizes. When it is necessary to reduce the number of heat sink bodies 7 inside the first fixing plate 1 or the second fixing plate 2, the user first pushes the disc 14 to move on the right side of the connecting plate 9. While the disc 14 moves, it drives the push rod 104 to move inside the through hole 15, and at the same time, it drives the fixing block 102 and the locking block 101. As the moving, fixing block 102 and locking block 101 move, the compression spring 103 contracts inside the groove 17. As the locking block 101 moves, it is pulled out of the positioning block 8. At the same time, the user pulls the connecting plate 9 to move. As the connecting plate 9 moves, it pulls the heat sink body 7 out of the placement slot 11. This can reduce the number of heat sink bodies 7 inside the first fixing plate 1 or the second fixing plate 2. Conversely, under the elastic force of the spring 103, the heat sink body 7 can be fixed inside the first fixing plate 1 or the second fixing plate 2, which can increase the number of heat sink bodies 7 inside the first fixing plate 1 or the second fixing plate 2. This makes it convenient for the user to assemble or disassemble the heat sink body 7 according to actual usage needs, thereby improving the versatility of the heat sink body 7.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
